The difference between Q235A and Q235B
A and B in Q235A and Q235B in low alloy steel are the differences of quality grades. The most important difference is whether the impact test at room temperature is needed. A does not need to be done and B needs to be done. There are some subtle differences between Q235A and Q235B:
Chemical composition: Q235A: C:0.14~0.22: Mn: 0.30~0.65;S: 0.050Q235B: C:0.12~0.20: Mn: 0.30~0.70;S: 0.0452. Mechanical properties: there is no difference between tensile test, impact test A is not done, 20 degree impact test B, V impact work (longitudinal) J is not less than 27.
The strength is the same, only the mechanical and chemical properties have some differences.Generally speaking, in the southern region, it is feasible to adopt Q235a for non-welded components without dynamic load.It is feasible to adopt Q235a for the welded components without dynamic load, but the carbon content <=0.2% should be guaranteed, mainly ensuring the weldability.Q235b is generally used for welded, dynamic loading structures.The choice of steel, visible "steel structure design manual" a book.
Q235 is a common carbon structural steel. Its yield point is greater than 235MPa. Its quality grade is divided into four grades: A.B.C.D., which are improved in turn.Number, its meaning is Q235A ingredients: C - 0.14-0.22, Mn - 0.30-0.65, the Si - 0.3-0.05 S, p - 0.045Q235B ingredients: C - 0.12-0.20, Mn - 0.30-0.70, the Si - 0.3, S P - 0.045-0.045The above contents of alloying elements are all percentages.
